The Cardley-Wave system, which uses water heated to a temperature of 98 degsC, was launched in Bristol - European Green Capital 2015 - at the end of last month.
The Cardley-Wave company, based in Lancashire, said its "range of manual and machine-mounted systems all offer an environmentally friendly, non-chemical weed-killing strategy, eradicating the plant and exhausting the root of the weed".
The units also enable operators to carry out deep cleansing duties where they can kill moss and remove gum and dirt while wiping out weeds, according to the firm.
The launch followed the publication of the UK's first integrated pest management guidance for amenity.
Weeds: Best Practice Guidance Notes for Integrated & Non-chemical Amenity Hard Surface Weed Control is the result of a five-year scientific study commissioned by Defra, run by East Malling Research and hosted by Kent County Council on the streets of Thanet.
The guidance studied amenity use of herbicide, non-herbicide and integrated approaches to weed removal.
